   CERTIFICATION PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Scott R. Silverman, certify that:

1. I have reviewed Amendment No. 1 to this quarterly report on Form 10-Q/A of
Applied Digital Solutions, Inc.;

2. Based on my knowledge, this report does not contain any untrue statement
of a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this report;

3. Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects
the financial condition, results of operations and cash flows of the
registrant as of, and for, the periods presented in this report;

4. The registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined
in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over
financial reporting, (as defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for the registrant and we have:

         a) Designed such disclosure controls and procedures, or caused such
         disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to the
         registrant, including its consolidated subsidiaries, is made known
         to us by others within those entities, particularly during the
         period in which this quarterly report is being prepared;

         b) Designed such internal control over financial reporting or
         caused such internal control over financial reporting to be
         designed under our supervision, to provide reasonable assurance
         regarding the reliability of financial reporting and the
         preparation of financial statements for external purposes in
         accordance with generally accepted accounting principles;

         c) Evaluated the effectiveness of the registrant's disclosure
         controls and procedures and presented in this report our
         conclusions about the effectiveness of the disclosure controls and
         procedures as of the end of the period covered by this report based
         on such evaluation; and

         d) Disclosed in this report any change in the registrant's internal
         control over financial reporting that occurred during the
         registrant's most recent fiscal quarter (the registrant's fourth
         fiscal quarter in the case of an annual report) that has materially
         affected, or is reasonably likely to materially affect, the
         registrant's internal control over financial reporting.

5. The registrant's other certifying officers and I have disclosed, based on
our most recent evaluation of internal control over financial reporting, to
the registrant's auditors and the audit committee of the registrant's board
of directors (or persons performing the equivalent function):

         a) All significant deficiencies and material weaknesses in the
         design or operation of internal controls over financial reporting
         which are reasonably likely to adversely affect the registrant's
         ability to record, process, summarize and report financial
         information; and

         b) Any fraud, whether or not material, that involves management or
         other employees who have a significant role in the registrant's
         internal control over financial reporting.
